Perillyl Alcohol + Warfarin
Warfarin brand name: Warfarin.
We found no known interaction between Perillyl Alcohol and Warfarin in our sources. Absence of a documented interaction is not the same as proven safety, and does not guarantee one does not exist. Do not start, stop, or change a medication or supplement based on this page; confirm with your pharmacist or doctor first. Additionally, although there is no interaction, the two are separately associated with some of the same side effects, which would make a new symptom harder to attribute to one or the other.
Perillyl Alcohol and Warfarin
We checked these two against our interaction database. Here is what we found.
No Known Interaction Found
We did not find a documented interaction between Warfarin and Perillyl Alcohol in our sources. This does not guarantee that the combination is completely free of risk — there is often limited research on supplements and herbal products, especially around drug interactions.
Worth understanding: our licensed dataset holds no drug-interaction record for Perillyl Alcohol at all — not against Warfarin, and not against any other medication we track. This verdict therefore rests on the absence of any recorded data, not on research that looked at this combination and found nothing. We cannot rule an interaction out.
If you decide to take both, the practical routine is simple: add one new thing at a time and note the date you started it. If the combination is going to disagree with you, it usually shows in the first days to a couple of weeks — and a start date turns “I’ve been feeling off” into something a pharmacist can actually work with. Do not stop a prescribed medicine on your own.
Always talk with your pharmacist or doctor before making changes to your medications or supplements, particularly if you take several medications or have an ongoing health condition.

Questions About Perillyl Alcohol or Warfarin
These are real questions from readers, answered by the pharmacists at HelloPharmacist — written by a person, not generated from a database. Each one covers Perillyl Alcohol or Warfarin, not necessarily both, but if one is close to what you were about to ask it will usually go further than a database entry can:

From our pharmacist’s overview on the Warfarin page
“People take warfarin to prevent dangerous clots, and many are the same people reaching for glucosamine for sore joints or a multivitamin containing vitamin K, which makes this a list that deserves genuine respect. Of the 361 supplements on file for warfarin, 16 carry a major rating, and the danger runs in both directions: some add to w…”

Where Perillyl Alcohol and Warfarin Sit Against Everything Else
Out of every supplement and medication people look up on HelloPharmacist, here is where these two land this week — and which way each has been moving.
#1,366 of 1,452 supplements looked up here in the last 7 days
#4 of 2,830 medications looked up here in the last 7 days
Position among everything looked up on this site, not a measure of how commonly either one is used or how important it is. A supplement can climb this list because of a news story. It counts every request to the page, automated ones included, and nothing here identifies anyone.
Where does our data come from?
- Source: the Natural Medicines (TRC Healthcare) clinical database — the evidence-graded professional reference for herb & supplement interactions.
- Citation library: 103,510 references behind our interaction content, 65,311 of them resolved to verified PubMed/DOI sources. See every Perillyl Alcohol reference on this page ↓
- Freshness: we automatically re-check this combination every week — this pair was last verified September 13, 2026. The Perillyl Alcohol and Warfarin records this page draws on were last updated July 10, 2026.
- What “no known interaction” means: no documented interaction in the sources above — not a guarantee of safety. Supplements are studied far less than prescription drugs, so we say exactly what the evidence supports, and nothing more.
About Perillyl Alcohol
What is Perillyl Alcohol?
- Cancer research (investigational)
- Antioxidant interest
- General wellness supplement
- Aromatherapy-related products
Perillyl alcohol is a natural compound found in the essential oils of plants like mint, lavender, and citrus, and it has mainly been studied as an experimental anti-cancer agent rather than as an everyday supplement. The evidence in people is limited and still under investigation, so it should not be used to treat or prevent any disease without medical supervision. Talk to your pharmacist or doctor before trying it.
Naturally found in the essential oils of plants such as lavender, peppermint, sage, cherries, and citrus fruits; often produced from limonene · Capsules, oral liquid, and (in research settings) intranasal preparations
An interaction check asks whether these two react with each other — it does not ask whether Perillyl Alcohol is a good idea for someone in your situation. Here is what our Perillyl Alcohol record says about it on its own.
Perillyl Alcohol: dosing
There is no established standard supplement dose of perillyl alcohol for the general public. The doses used in research were chosen for clinical trials and were given under close medical supervision, so they do not apply to over-the-counter use.If you choose to use a product that contains perillyl alcohol, follow the directions on the product label and do not exceed them.

About Warfarin
What Is Warfarin Used For?
Brand name: Warfarin
Warfarin sodium tablets and Jantoven tablets are both used to prevent and treat venous thrombosis (blood clots in the veins) and pulmonary embolism (a clot in the lungs). They are also used to prevent clot-related complications in people with atrial fibrillation (an irregular heart rhythm) or who have had a heart valve replaced.
In people who have had a heart attack, warfarin is used to reduce the risk of death, another heart attack, stroke, or other clotting events. It does not dissolve an existing clot, but it helps prevent the clot from growing and stops new dangerous clots from forming.
